The project entailed the administration of a detailed field-level survey to farmers in 12 watersheds in the Nation to gather data on agricultural practices, input use, and natural resource characteristics associated with farming activities. The data were analyzed by the Economic Research Service using a consistent methodological approach with the full set of data to study the constraints associated with the adoption of micronutrients, N-testing, split nitrogen applications, green manure, biological pest controls, pest-resistant varieties, crop rotations, pheromones, scouting, conservation tillage, contour farming, strip cropping, grassed waterways, and irrigation. In addition to the combined-areas analyses, selected areas were chosen for analysis to illustrate the difference in results between aggregate and area-specific models. The unique sample design for the survey was used to explore the importance of field-level natural resource data for evaluating adoption at both the aggregate and watershed levels. Further analyses of the data illustrated how the adoption of specific management practices affects chemical use and crop yields.","PeriodicalId":267426,"journal":{"name":"Agricultural Economics Reports","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116328441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional alternatives for procurement range from spot purchases with specifications for easily measurable characteristics, to varying forms of strategies with pre-commitment. In the case of grains these choices are complicated by two factors. First, there is intrinsic uncertainty associated with end-use qualities that are not easily measurable. Second, grain prices and therefore procurement costs vary spatially due to competing market regions. Thus, shifting origins may involve higher cost due to having to bid grain away from its next best market. We posed three procurement strategies and developed analytical models to evaluate the risks and costs among these alternatives in the case of hard red spring (HRS) wheat. The first involves no commitment. The second involves some form of irrevocable commitment and the third entails less commitment. Stochastic simulation models were developed for each with an objective of cost minimization subject to different levels of risk. The results indicate that the naive strategy has the lowest expected cost, but a fairly high probability of not conforming to end-use requirements. The constant share strategies result in higher probabilities of meeting requirements, but at substantially higher costs. The opportunistic strategy results in a higher probability of meeting requirements than either of the other two alternative strategies at a comparable cost.","PeriodicalId":267426,"journal":{"name":"Agricultural Economics Reports","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
